1. A monitoring system for an aircraft engine, comprising:

  • a plurality of wireless engine sensors mounted on the aircraft engine and each configured to sense an engine parameter and engine data and transmit wirelessly the engine data and receive engine data to change the respective operation of the engine parameter sensing;

    an engine monitoring module comprising;

    a housing configured to be mounted at the aircraft engine,a first wireless transceiver carried by the housing,a memory carried by the housing,a processor carried by the housing and coupled to the memory and the first wireless transceiver and configured to;

    collect and store in said memory engine data relating to at least one engine parameter sensed during operation of the aircraft engine by the plurality of engine sensors and transmit the engine data via the first wireless transceiver over a wireless communications signal;

    a wireless local area network (LAN) communications unit located within the aircraft and forming a wireless access point and wireless LAN within the aircraft, the wireless LAN communications unit including a processor and a wireless communications unit configured to receive the wireless communications signal via the wireless LAN and retransmit the engine data received from the engine monitoring module, and said communications unit further configured to receive and process within the processor data regarding engine sensor operation of at least one engine sensor and transmit back to the engine monitoring module data regarding engine parameter sensing in the at least one engine sensor, wherein selected ones of the plurality of wireless engine sensors receive the data regarding engine parameter sensing and change the operation of a respective sensor for a different engine parameter sensing operation; and

    a second wireless transceiver located within the aircraft and configured to receive the engine data via the wireless LAN over a wireless communications signal from the wireless communications unit and transmit the engine data over a wireless communications signal from the aircraft.
